WCF超時問題

Question

我有以下代碼

public bool StartWCF() 
    { 
     try 
     { 
      // Select the first entry. I hope it's this maschines IP 
      // IPAddress _ipAddress = ips.AddressList[0]; 
      var ipAddress = new IPAddress(new byte[] { 127, 0, 0, 1 }); 

      // Create the url that is needed to specify where the service should be started 
      this.m_UrlMetaServiceComm = "net.tcp://" + ipAddress + ":8000/VSMDBCommunication"; 
      this.m_UrlMetaServicePart = "net.tcp://" + ipAddress + ":8000/VSMDBPartType"; 

      string endPointAddrComm = this.m_UrlMetaServiceComm; 
      var tcpBindingComm = new NetTcpBinding 
       { 
        TransactionFlow = false, 
        MaxReceivedMessageSize = 20000000, 
        MaxBufferSize = 20000000, 
        MaxBufferPoolSize = 20000000, 
        ReaderQuotas = { MaxNameTableCharCount = 20000000 }, 
        OpenTimeout = new TimeSpan(0, 5, 0), 
        SendTimeout = new TimeSpan(0, 5, 0), 
        CloseTimeout = new TimeSpan(0, 5, 0) 
       }; 
      tcpBindingComm.Security.Transport.ProtectionLevel = ProtectionLevel.EncryptAndSign; 
      tcpBindingComm.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows; 
      tcpBindingComm.Security.Mode = SecurityMode.None; 

      var endpointAddressComm = new EndpointAddress(endPointAddrComm); 
      this.m_ChannelCommunication = ChannelFactory<IVSMDBCommunication>.CreateChannel(
       tcpBindingComm, endpointAddressComm); 
      ((IContextChannel)m_ChannelCommunication).OperationTimeout = new TimeSpan(0, 5, 0); 
      string endPointAddrPart = this.m_UrlMetaServicePart; 
      var tcpBindingPart = new NetTcpBinding 
       { 
        TransactionFlow = false, 
        MaxReceivedMessageSize = 20000000, 
        MaxBufferSize = 20000000, 
        MaxBufferPoolSize = 20000000, 
        ReaderQuotas = { MaxNameTableCharCount = 20000000 }, 
        OpenTimeout = new TimeSpan(0, 5, 0), 
        SendTimeout = new TimeSpan(0, 5, 0), 
        CloseTimeout = new TimeSpan(0, 5, 0) 
       }; 
      tcpBindingPart.Security.Transport.ProtectionLevel = ProtectionLevel.EncryptAndSign; 
      tcpBindingPart.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows; 
      tcpBindingPart.Security.Mode = SecurityMode.None; 

      var endpointAddressPart = new EndpointAddress(endPointAddrPart); 
      this.m_ChannelPartTypes = ChannelFactory<IVSMDBPartType>.CreateChannel(
       tcpBindingPart, endpointAddressPart); 
      ((IContextChannel)m_ChannelPartTypes).OperationTimeout = new TimeSpan(0, 5, 0); 
      return true; 
     } 
     catch (CommunicationObjectFaultedException faultEx) 
     { 
      // System.Diagnostics.Trace.TraceError(faultEx.ToString()); 
      Console.WriteLine("An unknown exception was received. " + faultEx.Message + faultEx.StackTrace); 
      Console.Read(); 
      return false; 
     } 
     catch (EndpointNotFoundException endEx) 
     { 
      // System.Diagnostics.Trace.TraceError(endEx.ToString()); 
      Console.WriteLine("An unknown exception was received. " + endEx.Message + endEx.StackTrace); 
      Console.Read(); 
      return false; 
     } 
    } 

，我偶爾會碰到下面的錯誤當底層過程需要超過一分鐘。

消息：

發送到 的net.tcp此請求操作：//127.0.0.1：8000/VSMDBCommunication 沒有收到 配置的超時（00:01:00）中的答覆。分配給此操作的 時間可能是 已超時的更長時間的一部分。這可能是因爲 服務仍在處理 操作或因爲服務是 無法發送答覆消息。 請考慮增加 操作超時（通過強制 通道/代理轉換爲IContextChannel和 設置OperationTimeout屬性） ，並確保該服務能夠 連接到客戶端。

如何以不同於我爲避免此錯誤的方式來投射頻道，這很有意義，因爲底層請求可能需要一分多鐘才能計算。

Answer 1

嘗試設置ReceiveTimeout屬性。

Answer 2

設置客戶端操作超時爲

client.InnerChannel.OperationTimeout = TimeSpan.FromMinutes(10); 

這將刪除你的錯誤。
